Hi, I bought a 2003 GTP LE, nice car, I've owned a number of Pontiacs over the years, including a 95 GP, but I've never owned a supercharged 3.8, any advice on maintaining the motor or supercharger?
Also, a few specific questions,
1. the door to the gas cap is damaged, is this easy to replace?
2. should I change the oil in the SC? how often?
3. What is the preferred exhaust system upgrade for these motors?
Thanks much...

Gas Door ya not too bad. Just get one from a junk yard.
Change the oil in the SC every 30k. Get a windex bottle and use he sprayer to suck out the old nasty fluid and squirt it into a bottle to be thrown away. It will smell like rotten ass! Get more SC fluid from your local GM dealership.
Preferred Exhaust system is stock. If you want it more noisy then add aftermarket mufflers.
If you want it to flow better get Headers.

Thanks much Rynoman... Looks like the gas door is attached by one screw, agree?
